This is definitely a fast B8 S4 and the same vehicle that pulled pretty well on a bolt on E92 M3 at a recent air strip roll on racing event. So, it's faster than a bolt on manual M3 but what about a tuned E92 335i? The result is not pretty for the 335i either with the S4 walking away. Fortunately, the race is not just an exterior view but also features a picture in picture view from the S4 to give perspective. The race is a half mile long from approximately a 40 mile per hour roll.

Unfortunately, the mod list on the E92 335i is unknown other than it is said to have a Stage II tune. Whose tune? What fuel? What supporting mods? Well, these all make a big difference. Fact is though this GIAC tuned car walks away from this particular 335.

something doesn't seem right...I mean you throw on some double-sided tape faux carbon fiber trim in the car. It's modded, no? Was this clip from an Audi forum?
It definitely got away from the 335, thats for sure.

We can't officially release the figures yet since the pulley isn't available yet. But Stage 1 put down 400-410 at the wheels on our Mustang dyno. This is more than the Stage 2 335i's we have dyno'd, although the S4 will put down less torque.

The pulley'd S4 is very fast, as when the car was Stage 1 at the last Shift Sector it was losing by multiple car lengths to Stage 2 N54's. The upgraded pulley and Stage 2 software is a night and day difference.

I'd say so, that $#@! moved out nicely, like it should walk away from single turbo 335i's nicely. I cant see that unless there is really THAT much headroom in that blower.
